The son of a jailed Hamas leader who converted to Christianity and moved to California has gone public to say that he spied for Israel.
Speaking before the release of a book about his life, Mosab Hassan Yousef made the assertion in an interview for Israel’s Haaretz newspaper.
A former deputy head of Israel’s Shin Bet intelligence service told the BBC he had been one of its agents.
Mr Yousef, 32, is a son of Sheikh Hassan Yousef, a senior Hamas figure in the West Bank, who is currently serving a six-year prison sentence in an Israeli prison.
A Hamas leader dismissed the report as a slander on the Islamist group. If the younger Yousef’s revelations are true, and he did play a role in preventing Hamas attacks on Israel, it will be an embarrassment for the group, which prides itself on its tight discipline and shuns the Palestinian Authority because of its peace negotiations with Israel.
